The commentary on the Apostles’ Creed, a confession of Christian faith, composed between the 4th and the 8th centuries by Rufinus of Aquileia and Pirmin of Reichenau, makes it possible to understand the elaboration of Christian doctrine from the beginning of the Church

Against the warning of Isaiah against alliances that lead to idolatry and its prophecies on the end of Israel, Judah and the great empires, Israel is contending : God does nothing to defend his rights. But the Creator God, eternal, unfathomable, is God from all eternity. He lives and acts infinitely beyond human limitations. He directs the nations according to his will. To those who do not rely on their own abilities but trust in him, he gives the courage, strength and patience to overcome the difficult moments, not to weaken but to continue.
